Since Mercury is having a hard time keeping up with demand of the current supercharged Verado line, I doubt we will see anything soon to replace it. Ramping up production of their new 3.4L V6 and 4.6L V8 outboards will likely take most of their effort for the next few years. I can't even imagine the physical manufacturing undertaking they are going through right now, in addition to pumping out mass quantities of the existing Verado line. We should be happy with what we have from them right now, it's pretty amazing that 120+ mph 30' - 36' twin outboard cats are commonplace now!

sorry Hogie, I didn't mean to falsely take credit for that math. I got that math from the internet. You see I drive for a living I make deliveries and wished that I stayed in school. That's one of the things I regret most is not staying in school.
Maybe I should delete this thread because I don't mean to mislead anyone

There won’t be a 707hp supercharged version imo.
I’d bet they’ll take it to 500 though.
i6 is built like a brick **** house and pretty heavy. V8 is light weight. I’d be shocked if they took it to the same specific output.

The current V8’s do not have any plans for supercharging for the near future. Currently, the Verado I6 block is being redesigned to be a full cast block, without liners, which will increase displacement, growth in HP, and decrease weight. Im currently selling Mercury new cutting tools for the production of this evolved platform. The I6 is just so bulletproof and successful that Merc will keep this platform for the long term. Stay tuned.

Im a big fan of O/Bs being two Stroke like the e-tec's but Merc just rewrote the rules w/their new V-8.
I have a friend repowering a 30' I/O vee to O/Bs and was ready to order a pair of 400r Verados and was told to wait for the upcoming 500 hp V-8.
Once there, I can't see them continuing production of the I-6.
Less displacement and more weight.
One of OMCs problems in the '80's was they offered two versions of their 200 - 225/235's in V-6 configuration at the same time when the consumers knew no difference.
At HUGE cost to them.

Wishful thinking for a 500hp v8. Mercury will not jump 100hp. Expect a 450hp to start. They need to have this platform last for years to come. I would guess it weigh less than the current 400r.

Here is my take on it and if you look at it from a business standpoint mercury profits will be too the roof.
Mercury will have a 450x using all the internals and technology from the current Verado setup but use the v8 block technology to make the setup lightweight maybe 550lbs. No research and development needed because they already have a proven system we just made it lighter but we're going to sell it for $38k.
The v8 is a great platform to bore and stroke to make more power but manufacturing of new parts would cost.

Cant comment on Mercury but from engine design, you need to pull compression with a FI engine in order to make it last. Typically you see between .7-.8 power more with FI then NA. For instance if you took a 300hp engine at sea level and forced 14.7psi thru it, you should double the power(double atmospheric pressure), but you have to pull compression in order to make the engine last along with timing to run on pump gas. At 300hp at 14.7psi one would see 510hp. Not sure what the 400r runs for manifold pressure to achive the 400hp but typical in a gas application you wont see much more then 1bar of manifold pressure on pump gas.
Short answer I'm guessing around 500hp.
